Abstract

Purpose In recent years an earlier step down to oral antibiotic therapy has been advocated for numerous infections. Trained infectious disease specialists regularly consulting their colleagues may speed up the implementation of such recommendations into clinical practice and thus may improve treatment. Methods We retrospectively analyzed bone and joint infections in children admitted to the University Hospital of Cologne between 2010 and 2021. We assessed clinical, imaging, and microbiological findings and treatment modalities. Additionally, we assessed both the impact of a newly implemented pediatric infectious diseases consultation service and publications on revised treatment recommendations by comparing antibiotic therapy in two periods (2010-2016 versus 2017 to 2021). Results In total, 29 children presented with osteomyelitis, 16 with bacterial arthritis and 7 with discitis. In period 2 (2017-2021) we observed shorter duration of intravenous treatment (p = 0.009) and a higher percentage of oral antibiotic treatment in relation to the total duration of antibiotics (25% versus 59%, p = 0.007) compared to period 1 (2010-2016). Yet, no differences were identified for the total length of antibiotic treatment. Additionally, biopsies or synovial fluid samples were retrieved and cultured in more children in period 2 (p = 0.077). The main pathogen identified in osteomyelitis and bacterial arthritis was Staphylococcus aureus (MSSA), diagnosis was confirmed predominantly with MRI. Conclusion Recent guidelines addressing the safety of an earlier step-down (to oral) antibiotic therapy have influenced clinical practice in the treatment of bone and joint infections in our hospital. A newly implemented pediatric infectious diseases consultation service might have accelerated this progress resulting in a faster step down to oral treatment.
